Nostrils going upwards when smiling, can the nostrils muscles be cut from the cheek so the nostrils remain downwards? (Photo)

Hello and thank you for your question. Based on your photograph, you may benefit from a tip refining rhinoplasty. Your surgeon can accomplish this by trimming, suturing, and reshaping the cartilage in your lower nose. Your nose is drooping with smiling because of poor tip support and this can also be improved with surgery. With good surgical technique, you could have an outstanding result. I recommend that you seek consultation with a qualified board-certified plastic surgeon who can evaluate you in person.

Best wishes and good luck.

What you describe is not a viable option.
We generally do not make dynamic assessments in plastic surgery.
The impact of contracting muscles of facial expression is best left alone.
The only exception to this is the use of Botox, which is generally most indicated in the forehead, and around the eyes.
Paralyzing your smile, muscles will lead to an appears of having had a stroke.
Best,
